This week, UK particle physicists have demonstrated the worlds largest, working computing Grid. With over 6,000 computers at 78 sites internationally, the Large Hadron Collider Computing Grid (LCG) is the first permanent, worldwide Grid for doing real science. The UK is a major part of LCG, providing more than 1,000 computers in 12 sites. At the 2004 UK e-Science All Hands Meeting in Nottingham, particle physicists representing a collaboration of 20 UK institutions will explain to biologists, chemists and computer scientists how they reached this milestone.
Particle physics experiments at the Large Hadron Collider (LHC), currently under construction at CERN in Geneva will produce around 15 Petabytes of data each year - 15 million, billion bytes. To deal with this vast volume of data, particle physicists worldwide have been building a computing Grid. By 2007, this Grid will have the equivalent of 100,000 of todays fastest computers working together to produce a virtual supercomputer, which can be expanded and developed as needed. When the LHC experiments start in 2007, they are expected to reveal new physics processes that were crucial in building the Universe we see today, and shed light on mysteries such as the origin of mass.
Grid computing has been a target for IT developers and scientists for more than five years. It allows scientists to access computer power and data from around the world seamlessly, without needing to know where the computers are. Analysis for particle physics can also be done on conventional supercomputers, but these are expensive and in high demand. Grid computing, in contrast, is constructed from thousands of cheap units that can be increased to meet users needs. Like the web before it, the Grid has the potential to impact on everyones computing.

NASA keeps watch over space explosions

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
